Polymerization
Signs of polymerization of stored material include container bulging, leaking, and the emission of heat, or an unusual odor
from the container. If you notice this, do not use the material and dispose of it properly.
Never mix different materials.
MATERIAL DISPOSAL
Because stereolithography materials are regulated, they are subject to special disposal requirements by your local, federal,
or other regulatory agencies. Follow applicable disposal guidelines. Contact a local waste management company for
recommendations on disposal requirements that affect your facility.
Do not leave uncured or liquid materials in an area where persons who are not knowledgeable about their handling or use may
have access to them. If your area requires regulated waste disposal, consult with and retain a waste management company to
periodically pick up regulated waste. Your local waste management company may recommend that you set up a drum, or other
approved container, to dispose of liquid print material and of any materials (such as paper towels or gloves) that may have
come into contact with the uncured liquid print material.
After part printing in the SLA system, the parts are not yet fully cured, and must be post-cured using the PostCure 1050. After
an adequate period of UV light exposure in the PostCure 1050, the parts should be fully solidified and then may be handled
without the precaution of gloves.
Note: Inspect your parts after curing in the PostCure 1050 to ensure they are fully solidified. Part surface
tackiness, visible or discernible areas of liquid resin indicate the part is not fully cured.
MATERIAL SPILL CONTAINMENT
Your company has the responsibility to define what constitutes a major spill. Personnel who are involved in cleaning up major
spills of material should wear NIOSH/MSHA approved respirators designed for use with organic chemical vapors. In addition,
each person should wear protective goggles, rubber boots, and 100% nitrile gloves to minimize exposure to material, which can
cause eye, skin, and respiratory irritation, as well as possible skin allergies and respiratory reactions.
A supply of dikes and control booms should be stocked so they are available to contain the affected area in the event of a major
material spill. The spilled material should then be absorbed on inert absorbent material and placed into drums for transfer to
an approved waste disposal site. After cleaning up the spill, individuals should wash thoroughly with soap and COLD water.
Dry-clean contaminated clothing. Discard contaminated shoes and leather products. Avoid exposure to sunlight until skin and
clothing have been cleaned of material. Refer to the MSDS/SDS before using any chemicals. Repeated or prolonged skin contact
may cause sensitization. Vapor may be harmful.
FIRST AID AND PROTECTIVE EQUIPMENT
The following paragraphs provide general first aid procedures and recommendations for protective equipment to minimize the
risks from material exposure. If professional medical attention is necessary, take the Material Safety Data Sheet / Safety Data
Sheet (MSDS/SDS) for the exact material involved to the attending physician.
Skin Contact
Wear 100% nitrile gloves and lab coats to avoid skin contact. Should material come in contact with skin, wash thoroughly with
soap and cold water and immediately remove contaminated clothing and shoes. If skin is irritated, seek medical attention. Dry-
clean contaminated clothing. Discard contaminated shoes and leather products.
Eye Contact
Safety goggles should be worn to prevent accidental splashes into the eyes. If material comes in contact with the eye, flush
immediately with large amounts of water for 15 minutes, avoid sunlight, fluorescent light, and other ultraviolet light, and obtain
immediate medical attention. Eye wash facilities and a first aid kit should be readily available and close to the material.
Contact Lenses
If material splashes into the eye when contact lenses are worn, flush the eye with water immediately. Verify that flushing has
removed the contact lens from the eye. Protect eyes from light and obtain immediate medical attention. Discard contact lenses
that come into contact with liquid material.
